React Component Profiling
Extensive guide on React performance optimalization in a real-world application

Serious rendering performance troubles in confac, our internal React invoicing app. It reads the entire database in memory 😲 and works pretty much exclusively on the frontend with the Redux store, so it’s not the db that is the performance bottleneck for once 😜

Worst case scenario on the /monthly-invoicing page is a whopping 10s wait time for a single screen to become responsive. Not good.

Hacking Tool: nmap
The free Network Mapper

Before Trinity could take down the electric grid, she had to find an attack vector. Her hack started with… nmap!


And then used an actual SSH exploit. Nmap can obviously do more than tell you whether SSH is on port 22 ;)

The itenium Slack Meme Bot® : with AI?
Implementation was easy enough. Is ChatGPT up for the task?

A few hours of fun, playing around with Docker, Cron, Node, Shell and a FileServer. Can ChatGPT do this too? And maybe in less time?

To be honest, I am very biased against ChatGPT but still hoping, very hard, that it can just do this, so that I can start using it for simple stuff, POCs and more!
